1 000 000 000 ppl have died since humans exist? Really? 1 Billion? There are about 6 000 000 000 ppl on this planet in this moment :-)

Right handed ppl in average live 9 times longer than left handed ppl? so when ppl live about 75 years in average today, do left handed only live a ninth of that in average (about 8-9 years) or do right handed live 600 years??
